Spanish workers have a 24-hour strike planned tomorrow that is expected to disrupt flights in and out of the country, causing severe delays. 20% of European flights are expected to be grounded as a consequence of the strike.

British Airways is giving passengers due to fly tomorrow the option of cancelling their flights with a full refund or re-booking for another date. Iberia said it will be operating 35% of its flights tomorrow; Ryanair will be operating hand-luggage only flights to Spain and will give a refund to passengers who had booked check-in luggage.

Ryanair has called on the European Commission to act to prevent further air traffic control strikes.

“Action must be taken at EU level to ensure that the ‘right to strike’ is removed from essential services such as ATC and competition must be introduced across Europe’s ATC providers to ensure that a strike in one country is not be allowed to disrupt million of passengers’ travel plans.” said Ryanair’s Stephen McNamara.

All passengers travelling to and from Spain tomorrow are advised to check their airlines’ websites for updates.
